In order to maintain a healthy weight, you need to eat enough calories to meet your needs. Your diet should also be low in fat, with about 30% coming from unsaturated fats. While it is tempting to replace animal fats with refined carbohydrates, this approach will not significantly lower your risk of heart disease, or improve your mood. Food manufacturers often hide large amounts of sugar and unhealthy fats in their processed foods, so you will want to choose natural, whole foods whenever possible. If you are eating out, try choosing a starter over an entree. If possible, split the dish with a friend. If eating at home, try to avoid the supersized items. You can also try serving your meals on smaller plates - a deck of cards is one serving, while a light bulb is one serving. This will trick your brain into thinking you are eating a much larger portion than you are. To make sure you are getting the recommended serving size, you can add a serving of leafy greens and fruit. While a healthy diet does not mean you should give up your favorite foods, a healthy eating plan should include some treats every now and then. Eating fresh fruits and vegetables, even vegetables, can be a treat, and it doesn't need to be expensive. If you're not sure what to eat every day, experiment with different foods and flavors until you find something that suits your lifestyle. Avoid eating the same burger or chips every day. When you go out to eat, try to limit high-fat and high-salt foods. Limit toppings if you can, and try to eat half of your plate full of vegetables each day. Even if you're not sure what to order, it's worth asking for a healthier option - it won't break the bank. Besides, you'll feel much more satisfied with your diet! It's that simple! Avoid highly processed foods like white bread and white rice. These foods are transformed from their original sources and have a number of additional ingredients. In addition, important nutrients are stripped out during the processing process, and they're replaced with salt and sugar. Some of these processed foods are high in fat and are harmful for your health. A good rule to follow when planning your diet is to add a 100-percent-DV multivitamin to your diet. For breakfast, you can eat a small slice of fruit with a serving of milk, yoghurt, or nut butter. A 150ml glass of juice is considered one portion, but eating more than this will damage your teeth. Another breakfast option is a small English muffin with some dried fruit on top. Fruits are also a great source of protein, and they contain several vitamins and minerals. You should make sure to include oily fish in your diet, as it is rich in omega-3 fats. Be aware that smoked and canned fish can be high in salt. While there are specific foods that improve mood and are known to be beneficial for health, a healthy diet should be based on a balanced diet, and the overall pattern of a person's diet. There are several types of healthy diets, and incorporating more real foods into your diet is a great way to improve your overall health. There are no hard and fast rules for eating a healthy diet, and you don't need to be a doctor to get one.
